scripts/db look fine

for core, i don't like the method, i would rather it be done any way other than a gigantic if/else
maybe another db column. look at how i did merit abilities for example

[kjLotus]

function curePotency(caster)

this function isn't needed, this is what MOD_CURE_POTENCY is for

[kjLotus]

can you split this patch into a few different ones? one for weaponskills, one for merits, etc
